How To Distinguish Between Stomach and Lung Blood?

April 5, 2026

Quick Answer

To distinguish between stomach and lung blood, look for the presence of stomach contents like leaves, twigs, or berries, and check for blood patterns indicating a lung hit, such as a large pool of blood or a trail that widens rapidly.

Identifying Stomach Blood

When tracking a wounded deer, stomach blood is often a sign of a non-fatal or shallow wound. Look for stomach contents like leaves, twigs, or berries stuck in the blood or surrounding vegetation. This type of blood is usually dark red to brown in color and can be found near the deer’s mouth or stomach area, typically within 10-20 feet of the initial wound.

Identifying Lung Blood

Lung blood, on the other hand, is often a sign of a more serious or penetrating wound. Check for blood patterns indicating a lung hit, such as a large pool of blood or a trail that widens rapidly. Lung blood tends to be brighter red in color and can be found in the deer’s chest area, often accompanied by a strong, metallic scent. When tracking lung blood, move quickly and decisively to locate the deer before it succumbs to its injuries.

Tracking Blood Trails

When tracking blood trails, remember that stomach blood tends to follow the deer’s path, while lung blood often indicates a more erratic or fleeing pattern. Take note of the blood’s color, consistency, and pattern to help determine the type of wound and the deer’s likely behavior. By paying attention to these details, you can increase your chances of locating the deer and making a clean harvest.
